| Outline of Final Research Achievements |
The following performance of topping work with sugar beet toppers decreases when the working speed increases. It is impossible to harvest at a high speed with conventional machines. This study aimed to develop new sugar beet topper using a 3D-CAD and CAE software.
The 3D model of conventional sugar beet topper was constructed on the CAD of a computer. The movement of topping mechanism of the test machine was simulated by the motion mechanism analysis software of the CAE. Real motions of the machine were captured with a high-speed video and simulator, and their motion trajectories were measured. The 3D-CAD and CAE were confirmed that it was possible to simulate the real motion of a conventional sugar beet topper to some degree. Moreover, the 3D-CAD and CAE of the simulation system proposed to enable a topping work faster than the conventional sugar beet topper. The topping performance of the modified machine in the high speed work was proven in the laboratory and the field experiment.
